Aerial Photography and Multispectral Remote Sensing for Engineering Soils Mapping. June 1969

摘要

The research investigated color aerial photography and other remote sensing techniques including multispectral imagery and their application to engineering soil mapping. The principal objectives were to study the incremental gain in information through the use of these techniques and to determine the cost savings if any. Other objectives included the investigation of some of the variables influencing the reflectance of materials and their diurnal thermal behavior, as it affects thermal imagery; and the generation of engineering soils maps by computer analysis of digitized multispectral data.
